ABSTRACT:
A circuit arrangement which comprises at least one stage which is to be fed by a source voltage from a common voltage source, at least one of these stages comprising a control signal generating circuit which can apply a control signal, to be derived from the source voltage, to a control signal output bus conductor which is common to all stages. A control signal input bus conductor can be connected to the control signal output bus conductor via a central bridge when the source voltage has a value within a first value range and which can be isolated from the control signal output bus conductor by the central bridge when the source voltage has a value within a second value range. Each stage includes a respective control circuit which can be connected to the control signal input bus conductor in order to receive the control signal and which can adjust the stage to a source voltage from the associated value range by application or interruption of the control signal. Thus, the circuit arrangement simply adapts the stages fed by the voltage source to the particular source voltage.
